Here's something that looks like a fake but isn't.
It is an old, plastic alarm clock with a Sonic theme. It is *Probably* a USA or possibly a UK item/it is unconfirmed. But, if you imagine it without the packaging...it looks kinda cheap and fake. The only 'Sonic' thing about the clock is the artwork on the face that is just cheap cardboard with the numbers on it. The clock itself is kind of shifty looking red plastic and extremely generic. This is a low-effort item...but the packaging is what confirms it's probably authentic.
The whole back card (since it's bubble-carded) is highly designed with chaos emeralds and rings flying everywhere, buzz bombers from Sonic 1 & then AOSTH early Robotnick in his egg o matic up there. The company seems to be called "Quartz Alarm", which is also a fairly generic name, but it's impossible to read anything else on the old package.

Bootleggers generally don't package items, don't do good package design if they do, and they espeically don't like having a company name on anything, nor will they bother with barcodes--which is what all of this has on it.
